AttributeError: 'Tensor' 对象没有属性 '_keras_history' [英] AttributeError: 'Tensor' object has no attribute '_keras_history'
问题描述
我查找了所有'Tensor' 对象没有属性 ***",但似乎没有一个与 Keras 相关(除了 TensorFlow: AttributeError: 'Tensor' object has no attribute 'log10' 这没有帮助)...
I looked for all the "'Tensor' object has no attribute ***" but none seems related to Keras (except for TensorFlow: AttributeError: 'Tensor' object has no attribute 'log10' which didn't help)...
我正在制作一种 GAN(生成对抗网络).在这里你可以找到结构.
I am making a sort of GAN (Generative Adversarial Networks). Here you can find the structure.
Layer (type) Output Shape Param # Connected to
_____________________________________________________________________________
input_1 (InputLayer) (None, 30, 91) 0
_____________________________________________________________________________
model_1 (Model) (None, 30, 1) 12558 input_1[0][0]
_____________________________________________________________________________
model_2 (Model) (None, 30, 91) 99889 input_1[0][0]
model_1[1][0]
_____________________________________________________________________________
model_3 (Model) (None, 1) 456637 model_2[1][0]
_____________________________________________________________________________
我预训练了 model_2 和 model_3.问题是我使用由 0 和 1 组成的列表对 model_2 进行了预训练,但是 model_1 返回了接近的值.所以我考虑使用以下代码对 model1_output 进行四舍五入:model1_out 上的 K.round().
I pretrained model_2, and model_3. The thing is I pretrained model_2 with list made of 0 and 1, but model_1 return approached values. So i considered rounding the model1_output, with the following code : the K.round() on model1_out.
import keras.backend as K
[...]
def make_gan(GAN_in, model1, model2, model3):
model1_out = model1(GAN_in)
model2_out = model2([GAN_in, K.round(model1_out)])
GAN_out = model3(model2_out)
GAN = Model(GAN_in, GAN_out)
GAN.compile(loss=loss, optimizer=model1.optimizer, metrics=['binary_accuracy'])
return GAN
[...]
我有以下错误:
AttributeError: 'Tensor' 对象没有属性 '_keras_history'
AttributeError: 'Tensor' object has no attribute '_keras_history'

我在 Windows 7 上使用 Python 3.6 和 Spyder 3.1.4.上周我用 pip 升级了 TensorFlow 和 Keras.感谢您提供的任何帮助!
I'm using Python 3.6, with Spyder 3.1.4, on Windows 7. I upgraded TensorFlow and Keras with pip last week. Thank you for any help provided !
推荐答案
我的问题是在 keras 上使用 '+' 而不是 'Add'
My problem was using '+' instead of 'Add' on keras
